Abstract

A method and system for efficiently conducting secure communications in a commuter network are provided. Secure communications in a network are typically of the Secure Socket Layer ('SSL') and Transport Layer Security ('TLS') formats. These formats require the server to decrypt numerous encrypted messages at the cost of efficiency and speed. By combining the encrypted messages into a batch and utilizing a Rivest-Shamir-Adleman ('RSA') batch decryption algorithm, the efficiency of the decryption is improved. Methods for improving this process include replacing the required number of divisions and inversion with more efficient multiplication operations. Further computation savings are realized by reducing the number of exponentiations and structuring the batches of encrypted messages to contain balanced exponents.
